The Colonnade in Northeast Kansas City. Experimenting again with infrared photography.

I compose and focus the image, then adjust the focus for infrared, add the filter to the front of the lens, and shoot. The filter blocks 100% of the visible light leaving only the infrared to reach the sensor. No way to meter the light so trial and error applies.

Above, this is what the image looks like coming right out of the camera, and, below, after adjustment in Photoshop.

Experimented with infrared photography today. Read online where the Nikon D800 was not usable for same, but then Roy Inman found an article online that said otherwise. Otherwise is correct. My IR filter is 67mm and I currently have no lenses of that diameter... so, had to hold the filter in front of my 50mm lens. Works but not optimal. I had forgotten how difficult IR can be.

Took this picture with the D70.... many of the Nikon cameras after that version have too good a filtration system which doesn't allow many of the IR rays through. Used a screw-on filter that blocks visible light and thus IR is all that hits the sensor. As you can see green records white and blue records black. This is a straight shot with no manipulation in Photoshop.
